These seem to be screenshots. where from? and why editing?

Are we sure those screenshots are from KLJ-7A display? I.e. the majority of that report has a lot of clips that are not from KLJ-7A.

can you provide bit more info or link to an article about it

The Americans call it a breakthrough, the French call it a game changer. Basically, it means the F-22 can be tracked from 100-200Km away with very high probability.

From the photos the antenna aperture seems to be more than 600 mm...can someone at Zhuhai confirm its horizontal and vertical dimensions?

Secondly what would be the Antenna's CANT angle once installed on JF17?...as AESA array contributes significantly towards aircraft RCS?

Than you guys should translate it for non chinese users..

I've translated it for non-Chinese user. Most Chinese are very whiny about translating English to Chinese. According to CCTV, KJ500 AWACS uses DESA.

I said it many times.JF-17 is a pure blood pakistan jet fighter.
we just help to make some upgrade parts.
pakistan is the few country which can build third generation jet fighters.

Bro get AESA first on yyour aircrafts then talk about some under development tech ...

This thread is about klj7a and not about yyour hypothetical claims ...

DESA.

Digital ESA, the next upgrade after Active ESA.

It is as big or bigger than the jump from PESA to AESA.

@randomradio
Sorry for being off topic,but LRDE's arudra and ashwin AESA radars feature digital beam forming.This is possible thanks to individual ADC modules attached at every antenna element. This is what renders true "multi-beam forming" capability.

If PAF select this KLJ-7A Radar for Block III of JF-17 will they also equip Block II's with it??

This is an absolute must Sir. Otherwise, you'd have around 100 jets in a 3rd generation category very prone to getting killed by their opponents with better tech like AESA. No air-force would risk a 100 jets over a few million worth of upgrade. At the least, you brought in serious force-multiplier capability through these upgrades. Thanks

You are right as it does make sense at least block 2 will have the same configurations as block 3 ,We should probably see these as MLU post 2020 as currently focus will be on numbers as 190-200 fighters need urgent replacement by 2020 .Just my thoughts

Keep all Aesa vs Desa vs Pesa discussions out of this thread. The thread is about klj7A so keep it that way.

Thanks, yeah, I'm aware of this. DESA on land based radars is quite old, goes back to the 80s. Putting those on aircraft now is a new phenomenon, particularly with GaN.

 

[optimisticlad]

any update on engine of new block to power this aesa radar

These are polish systems built by PIT, now RADWAR, and not designed in India.
